PET film is a film with excellent comprehensive properties. It has good transparency and gloss, good air tightness and fragrance retention, moderate moisture resistance of PET film, and reduced moisture permeability at low temperature.

PET film also has excellent mechanical properties, its strength is the best among all thermoplastics, and its tensile strength and impact strength are much higher than ordinary films. PET film has good strength and stable size, suitable for secondary processing such as printing and paper bags.

PET film also has excellent heat and cold resistance and good chemical resistance and oil resistance, but not strong alkali resistance.


Because of its many excellent properties, the application of Bopet film in different processing places is highly valued. PET film has stable and reliable performance during use, and the film is also very transparent. PET film has recycling value, does not impose a burden on the environment, and meets modern environmental protection requirements, so it has also begun to be widely recognized.

Although many people don’t know much about PET polyester film now. But at present, PET film has been used in many fields. The following introduces its application according to the characteristics of Bopet film:

High Temperature Resistance

PET film can resist high temperature, it can be used at higher temperature and can keep its original state. PET film can also achieve the ideal operation purpose when processed at high temperature, and its application rate has also been improved to a certain extent.

The high temperature resistance of PET film is especially suitable for the preparation of soldered electronic and electrical parts.

Good Insulating Properties

PET film is also a material with good insulating properties. Therefore, it can usually be used in the power industry. The use of polyester film in these processing and production sites can improve safety and facilitate the development of the power industry.

Because PET film has good insulating properties. It can be used for electronic components such as electronic transformers, relays, etc. that are resistant to high temperature and moisture-proof. It can also be used for bundling, insulating protection and fixing of cylindrical and square power battery pack shells.

Good Dimensional Stability

The performance of the polyester film produced now is very stable and reliable. The material can remain in its original state even in harsh environments. Therefore, the polyester film can be directly used by users in outdoor places.

The practical application of this material can not be limited by the environment, so compared with other materials, the introduction and application of Bopet film can solve many problems.

Hard Material, More Scratch-resistant

PET film plays an important role in the production of mobile phone screen protection materials, it can prevent the screen from being scratched and ensure product quality. Electronic products also need to be protected with PET materials. Therefore, the application of Bopet film in the electronic processing industry is very important.

As a protective film, PET film can be used as LCD TV protective film, mobile phone buttons.

Good Air Tightness

PET material also has a certain air tightness, and the resistance to humid environment is relatively high.

Along with the development of technology, a new PET barrier film – Alox coated PET film was also developed. This newly developed PET film has been developed as a potential replacement for natural food packaging needs.

Alox coatings typically consist of one or more of the following materials: silver, titanium, polyester, gold, indium tin oxide, or carbon. Additionally, some coated PET films include silver zinc coated films and tin oxide coatings.

This film can be used for products with high shelf life requirements.
